图2示出了介质接入控制(全称：Media Access Control，简称：MAC)层的功能结构图，MAC层支持的主要功能包括：逻辑信道与传输信道之间的映射；传输格式的选择，例如通过选择传输块大小、调制方案等作为输入参数提供给物理层；一个UE或多个UE之间逻辑信道的优先级管理；通过HARQ机制进行纠错；填充(Padding)；无线链路控制(全称：Radio Link Control，简称：RLC)协议数据单元(全称：Protocol Data Unit，简称：PDU) 的复用与解复用，业务量的测量与上报等。Figure 2 shows the functional structure diagram of the medium access control (full name: Media Access Control, MAC for short) layer. The main functions supported by the MAC layer include: mapping between logical channels and transport channels; selection of transport formats, for example Provided to the physical layer by selecting a transport block size, a modulation scheme, or the like as an input parameter; priority management of a logical channel between one UE or multiple UEs; error correction by a HARQ mechanism; padding; radio link control :Radio Link Control, referred to as: RLC) Protocol Data Unit (full name: Protocol Data Unit, PDU for short) Reuse and demultiplexing, measurement and reporting of traffic, etc.

MAC层提供给上层的业务主要包括：数据传送及无线资源分配。物理层提供给MAC层的业务包括：数据传送、混合自动重传请求(全称：Hybrid Automatic Repeat reQuest，简称：HARQ)反馈信令、调度请求信令以及测量。The services provided by the MAC layer to the upper layer mainly include: data transmission and radio resource allocation. The services provided by the physical layer to the MAC layer include: data transmission, Hybrid Automatic Repeat reQuest (HARQ) feedback signaling, scheduling request signaling, and measurement.

在上行链路中，终端设备的MAC层复用自己的多个上行链路数据流，并且决定是发送上行链路调度请求还是发送上行链路数据。在下行链路的共享信道，eNodeB必须考虑小区内发往所有用户设备的数据流(或者逻辑信道)。这就涉及到优先级处理过程，优先权处理是MAC层的一个主要功能。优先权处理过程是指从不同的等待队列选出一个分组，将其传递到物理层，并通过无线接口发送的过程。因为要考虑到不同信息流的发送，包括纯用户数据、E-UTRAN信令和演进分组核心网(全称：Evolved Packet Core，简称：EPC)信令，这个过程非常复杂。当已传数据没有正确接收时，是否重传也与优先权处理有关，所以优先权处理过程还是与HARQ密切相关的，HARQ是MAC的另一个主要功能。此外，网络设备的MAC层要负责上行链路优先权处理，因为它必须从共享UL-SCH传输信道的多个终端的所有上行链路调度请求消息中进行选择。In the uplink, the MAC layer of the terminal device multiplexes its own plurality of uplink data streams and decides whether to transmit an uplink scheduling request or transmit uplink data. On the shared channel of the downlink, the eNodeB must consider the data flow (or logical channel) sent to all user equipments within the cell. This involves the priority processing, which is a major function of the MAC layer. The priority processing process refers to the process of selecting a packet from a different waiting queue, passing it to the physical layer, and transmitting it through the wireless interface. This process is very complicated because it takes into account the transmission of different information streams, including pure user data, E-UTRAN signaling, and Evolved Packet Core (EPC) signaling. When the transmitted data is not correctly received, whether the retransmission is also related to the priority processing, so the priority processing is closely related to HARQ, which is another main function of the MAC. In addition, the MAC layer of the network device is responsible for uplink priority handling because it must select from all uplink scheduling request messages for multiple terminals sharing the UL-SCH transport channel.

应理解，图2所示的MAC实体的功能结构仅为一种示例，不应对本申请实施例构成任何限制。It should be understood that the functional structure of the MAC entity shown in FIG. 2 is only an example, and should not constitute any limitation to the embodiments of the present application.

图3示意性地示出了本申请实施例提供的传输数据的方法300。该方法300可以应用于上述无线通信***100，但本申请实施例不限于此。FIG. 3 is a schematic diagram of a method 300 for transmitting data provided by an embodiment of the present application. The method 300 can be applied to the wireless communication system 100 described above, but the embodiment of the present application is not limited thereto.

如图3所示，该方法300包括以下内容。As shown in FIG. 3, the method 300 includes the following.

在301中，发送端设备在多个MAC实体中确定发送待发送数据使用的MAC实体，所述待发送数据来自处于MAC层之上的第一协议实体，In 301, the sender device determines, in a plurality of MAC entities, a MAC entity that sends data to be sent, where the data to be sent is from a first protocol entity that is above the MAC layer.

在302中，通过确定的发送所述待发送数据使用的MAC实体发送所述待发送数据。In 302, the to-be-sent data is sent by the determined MAC entity that sends the to-be-sent data.

可选地，该多个MAC实体的功能结构可以为图2所示的MAC实体的功能结构，或者也可以采用其他形式的功能结构，本申请实施例对此不作限制。Optionally, the functional structure of the multiple MAC entities may be the functional structure of the MAC entity shown in FIG. 2, or other types of functional structures may be used, which is not limited in this embodiment of the present application.

由于业务需求的多样向，在物理层中引入了多种基础参数集传输技术，因此，在本申请实施例中，MAC层也可以相应地存在多个MAC实体，以支撑多种基础参数集机制。因此，相应地，从MAC层之上的高层向MAC 层传输数据时，由于存在多个MAC实体，需要选择传输数据使用的MAC实体。A variety of basic parameter set transmission technologies are introduced in the physical layer. Therefore, in the embodiment of the present application, multiple MAC entities may exist in the MAC layer to support multiple basic parameter set mechanisms. . Therefore, correspondingly, from the upper layer above the MAC layer to the MAC When the layer transmits data, since there are multiple MAC entities, it is necessary to select the MAC entity used for transmitting data.

具体地，发送端设备接收到来自MAC层之上的第一协议实体的待发送数据时，可以在该MAC层的多个MAC实体中确定用于发送该待发送数据的MAC实体，然后通过确定的该MAC实体发送该待发送数据。Specifically, when the sending end device receives the data to be sent from the first protocol entity above the MAC layer, the MAC entity for sending the to-be-sent data may be determined in multiple MAC entities of the MAC layer, and then determined.
